Sorry I did not it more specific, but yes. My RAM does have active airflow blowing over it from my CPU cooler.
I followed along with Hardware Unboxed's video and left it alone, with the tighter timings, for a few weeks. I soon got bored and decided to try improving my performance again and again. A few BSODs later, and BIOS clears, later I had managed to drop one of the RAM timings by one.
tCL 13 does not boot at all and 14 is completely stable, so I moved onto tRCDWR and tRCDRD and so on. I think I still have more room to tightening the timing further.
The reason why I am overclocking my CPU and tightening my Timings is because I noticed my GPU utilization rarely hits 95% let alone 100%. A good examples of this is Vermintide 2, the only time I get 100% GPU utilization is when I am staring at a wall, all other times my utilization hovers around 70% to 80%.
